connect with Java to Oracle without clear text password in code

Here an snipped of the code

public class ScriptOutput {

	private static String installPath = "//opt//jboss//tools//copy//";
	private static String host = "mz007542.internal.hosts", port =
"1521", sid = "ISSPDB",
			dbuser = "issdbuser", pw = "5s8yk5sbm3sj7";

	private static Connection cn;

	public static void main(String[] args) {

		try {
			Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
			String url = "jdbc:oracle:thin:_at_" + host + ":" + port + ":" + sid;
			cn = DriverManager.getConnection(url, dbuser, pw);


		} catch (SQLException e) {

			e.printStackTrace();


		} catch (InstantiationException e) {

			e.printStackTrace();


		} catch (IllegalAccessException e) {

			e.printStackTrace();


		} catch (ClassNotFoundException e) {

			e.printStackTrace();
		}
		createOutputOne();
		createOutputTwo();
		createOutputTree();
		createOutputFour();
	}

You see there is a clear text password for connecting to remote DB instance. I have no access to remote DB instance, only unprivileged user.
How to not write clear text password in the Java code (without modifying remote Oracle server)?

Any good ideas for better security? Please give detailed instructions because have almost no experience with Java.

cheers Sven
